SELF-CLOSING FAUCET.

Specification of Letters latent.

Application led July 17, 1911. Serial No. 638,817.

T o all whom 'it may concern.' v

Be it known that l. Gannon S. llvtisox, a citizen of the lnited States.residingr at Boston. county of Suffolk. State of Ma sachuqelf ClosingFaucets. of which the followingr description. in connection with theaccompanying drawing. is a specification, like characters on the drawingrepresent-in;- like parts.

This invention relates to self-tlosifr;r faucets and it. has for itsobject to provide a novel faucet. of this nature which will benon-leakable and which will automatically close itself whenever it isreleased by the. action of the water and gravity and without the use ofsprings.

Another object of my invention is to provide a faucet of this naturewhich requires no packing and which has few parts to wear or becomeinjured.

Another and important object is to provide a self-closingr faucet whichcan not be easily tampered with so as to prevent it from automaticallyclosing when it is released.

My improved faucet is especially designed for use where the water whichis supplied to houses is metered, and it.V will prevent the, waste ofwater by tenants. It thus is of economical benefit in all locationswhere it is desirable to conserve the. water supply.

The features wherein my invention resides will be first described inconnection with the accompanying drawings and then pointed out in theappended claim.

Referring to the drawings wherein I have illustrated a preferredembodiment of my invention Figure 1 is a vertical sectional view througha faucet embodying: my invention; Fig. 2 is a section on the line :1f-,Fig. 1.

The faucet comprises a body 1 having a valve seat 2 on which the'valve 3is adapted to be seated. said faucet having the usual screw-threadedconnection 4 by means of which it. may be screwed to a pipe or otherconnection. The valve 3 is provided with a projection 5 which extendsdownwardly through the valve seat and which is acted upon by an arm 6carried by a rockshaft 7 that is journaled in the body of the faucet,said rock-shaft extending beyond the faucet and having: on the endthereof a hand wheel 8 by which it. may be turned. When the hand wheel 8is thus turned the finger 6 is lifted and actingT against the projection5 will lift, tbe valve from its scat.

ln order to assist the valve to close antoinatically when the handle Sis released and also to prevent water hammer. l have asso ciated withthe valve two refraction disks which will now be described. The body ofthe faucet has extendingr upwardlyY therefrom above the valve seat 2 achamber li. and the valve is provided with a screwthreaded stein lf2which enters the chambre l1. Un this stem 12 are sustained two disio 9and 10. sai-.fl disks beiner preferably adjus' able on the stem '19. andheld in place by loef nuts 13. The disk 9 will preferably be positionedon the stem that when the valve is closed said disk will stand justbelow t: lower end of the chamber l1 and in line wir; the passage illeading to the'valve sei* The disk 1G is preferably placed conside ablyabove the disk 9 and both disks are of a size to permit the water topass around ther. as they move up and down. The chamber 11 is closed atits upper end b v means of a cap piece li which is screw-threaded intothe extension 15 in which the chamber i formed. This is a convenientconstruction because when the cap 1G is removed the valvi- 3 and disks 9and l() are easily accessible and can be readily taken out or replacedand when the cap 16 is screwed into the ex tension 15 a closed chamber11 is formed. In the particular embodiment shown the disk 10 is locatedwithin the cap 16 and is. therefore` somewhat. smaller than the disk 9.

In the operation of the device tbc valve is opened b v turning thehandle S thereby to lift the finger 6, and during this upward movementof the valve the water above the disks 9 and 10 will flow around thedisks as the disks move upwardly. lllhen .the handle 8 is released thevalve will close by the action of gravity and the disks 9 and l0 preventany sudden movement of the valve and thus prevent water hammer.Moreover. as the valve moves downwardly so as to bring the disk 9 belowthe point 17 a portion of the Water current will be deflected by saidkdisk 9-upwardly and thus the final seating movement of the valve will bean easy one und without any hammering action.

In order to prevent any person from inserting a wire or other implementup through the delivery passage 18 of the faucet and under the valve tokeep the latter open so as to prevent the valve from closing when thehandle is released, I have provided the deflecting projections 19 and 20which are formed on the interior of the discharge passage 18. Thedeflecting projection 19 is an the lower side of said passage andthe'de2 fleeting projection 20 on the upper side. These two projectionsare so situated relative to each other that it is not possible to inserta wire or other implement through the discharge passage 18 so as to makeit engage the valve and lift the latter from the seat and thus hold thevalve open. By making the disks 9 and 10 adjustable on the stem it ispossible to place them relative to each other and relative to the lowerend 17 of the passage 11 so that they will operate to prevent waterhammer and to cushion the downward movement of the valve as abovedescribed. I will preferably construct my faucet so that when the valveis fully open the disk 9 will rest against the lower edge of the cap1G,v said cap thus forming a stop to limit the opening movement of thevalve.

In order to prevent anyone from applying a clamp, wrench or other toolto the projecting portion of the shaft 7 and thereby holding the valveopen, I provide the body ofl the faucet with a protecting vtube 21through which Lhe shaft extends and which tube reaches from the faucetto the wheel 8, as clearly seen in Fig. 2. Ihis tube being stationaryprevents anyone from holding the faucet open by applying a tool to the 1shaft 7.

In order to facilitate the assembling of the parts I propose to make theportion 22 of the faucet in which the shaft 7 is journaled with anaperture 23 through which the finger 6 may be inserted, this aperturebeing closed by a plug 24. In assembling the parts the finger 6 isinserted through the aperture 23 until the hole in the finger is ina'linement with the shaft 7 and then the shaft-may be screwed into thefinger, said shaft being provided with a screw-threaded portion 25 forthis purpose. The iinger iS thus firmly held to the shaft.

An important feature of my invention relates to the refraction disks 9and 10 which break, refract and diverge the -force of the water so as tocheck .the gravitation of the valve and the waterv pressurel andallowythe valve to seat slowly, thus nreventing water hammer andstraining of t e pipes. Leakage around the shaft 7 and through the tube2l is prevented by siphonage.

The adjustability of the disks 9 and 10 permits the device to beadjusted to suit different conditions of water pressure.

While I have illustrated one embodiment of my invention I do not wish tobe limited to the construetional details shown.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent is:.-

In a faucet, the combination with a--faucet body having a 'valve seatand a chamber above said valve seat, of a valve having a` Ascrew-threaded stem extending into said chamber, and two refractiondisks adjustably carried by said stem, the lower disk being situated onthe stem so that it is located just below the lower end of said chamberwhen the valve is seated.

In testimony whereof, .I have signed my name to this specification, inthe .presence of two subscribing witnesses.
